FISHING-TOOL.

Specification of Letters Patent Patented Feb. 18, 1908.

Application filed November 11.1907. Serial No. 401.589

To all whom t may concern:

Be it known that we, WILLIAM HENRY BUTTON and ELBERT DYER, both citizensof the United States, and residents of Banden, in the county of Coos andState of Oregon, have invented a new and Improved Fishing- Tool, ofwhich the following is a full, clear, and exact description.

This invention is an improved tool for fishing out drills and other likedevices from oil wells, Artesian wells and other borings.

The object of the invention is to provide a tool vof this nature, whichwill operate to effectively grip tools which have been lost in borings,whether they be in an upright posi- `tion or have 'fallen over to oneside.

Reference is to be had to the accompanying drawings forming a part ofthis speciiication, in which similar characters .of reference indicatecorresponding parts in all the views.

Figure 1 illustrates in side elevation a iishing tool embodying ourinvention, showing the manner in which the same operates to remove fromthe boring a drill which has Jfallen over to one side Fig. 2 is acentral vertical sectional view of the lower portion of the tool; Fig. 3is a face view of the same; and Fig. 4 is a cross-section on the line 44 of Fig. 3 looking in the direction of the arrows.

The tool as preferably constructed is composed of two bars or sections 5and 6, jointedly connected together intermediate their length by thepivot-pin 7. The upper section 5, which is ordinarily the shortersection, is provided with the usual or other desired means forconnecting it to the drill-rod, and the lower section 6 is, at its lowerend, constructed with an enlarged semi-cylindrical or gouge-shaped head8; the latter being provided on its rear face, at each side of thecenter, with cut-out portions or slots 9 to avoid making the tool undulyheavy.

Within the head 8 and near the bottom end thereof are providedopposite-ly disposed gripping-jaws 10, having opposed serratedgripping-faces converging in an upward direction when in normalposition. These gripping-jaws 10 are pivoted in recesses formed in thewalls of the head, and are so balanced that they will normally assumethe position shown in Fig. 3, under the action of springs 10a, and inwhich position the under faces of the jaws rest upon the shoulders ofthe recesses in which they are movably mounted. As is 4best observed inFig. 3, the

opening in the front face of the head is of diminished width at thelower portion thereof, in order to provide sufficient metal for theouter bearings or pivots of the gripping-jaws.

The two sections ofthe tool are normally thrown out of alinement by aspring 11, which gives the tool a natural tendency to pass lineally overa drill which has fallen over to one side or occupies an angularposition with respect to the boring, as shown in Fig. 1. The spring 1lis rigidly attached to one of the sections of the drill and has asliding connection with the other section through an encircling ring orband 12.

It is apparent from the disposition of the jaws 10, that when the toolis lowered into the well, the said jaws will admit of the shank thereofpassing upwardly between them, and will swing on their pivots until thegripping-faces thereof are substantially parallel. On then drawing onthe tool, the jaws will bite into the drill and eiiectively grip thesame, whereby it may be withdrawn and removed.

The invention may obviously be modified in numerous particulars fromthat shown and described, and we consider that we are entitled to suchchanges as fall within the scope of the appended claims.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. In a tool of the character described, jointed sections, one of whichis provided with gripping means, and means normally operating to throwsaid sections out of alinement.

2. In a tool of the character described, a bar having a gouge-shapedhead, and gripping-jaws pivotally mounted within recesses of said headand having opposed grippingfaces normally converging upwardly.

3. In a tool of the character described, a bar having an enlarged headof substiantally semi-cylindrical form, and gripping-j aws pivotedwithin said head having opposed gripping-faces converging upwardly whenin normal position.

4. In a tool of the character described, a bar composed of two sectionspivoted together, means for attaching one of said sections to adrill-rod or the like, automatic gripping means carried by the othersection, and means operating to throw said sections out of alinement.

5. In a tool of the character described, a

bar composed of sections pivoted together, l bar composed of a pluralityof jointed sec- 15 gripping means carried by one of said sections, and aspring operating to throw said sections out of alinement.

6. In a device of the character described, a bar composed of twosections pivoted together, means for attaching one of said sections to adrill-rod or the like, automatic gripping means carried by the othersection, and a spring attached to one of said sections and having asliding connection with the other section and operating to throw said i'sections out of alineinent.

` 7. In a tool of the character described, a

tions, one of which is provided with a gougeshaped head, andgrippingjaws plvoted within said head having opposed grippingfacesconverging upwardly.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
